STACK vs. Sage Estimating
Ditch the Desktop. Embrace the Future.
STACK delivers AI-powered takeoffs, real-time collaboration, and cloud-based access—everything Sage Estimating can’t.
Why More Estimators Are Leaving Sage Behind
AI-Powered Takeoffs Save You Hours
Sage Estimating
Requires manual takeoff input and complex Excel exports.
STACK
Uses AI to accelerate takeoff creation, helping estimators generate accurate quantities in a fraction of the time.
Why does it matter?
STACK speeds up the process without sacrificing precision.
Collaboration in Real-Time
Sage Estimating
Built for single-user desktop experiences. Sharing requires cumbersome file transfers and version control issues.
STACK
Built in the cloud with multi-user collaboration, version history, and comment tracking so teams can work together in real time—wherever they are.
Why does it matter?
Miscommunication and outdated files slow your team down and cost you jobs. Real-time collaboration keeps everyone aligned and moving forward together.
One Platform for Takeoffs + Estimates
Sage Estimating
Works best when paired with other Sage products. Integrations and workflows can be rigid and costly.
STACK
Combines takeoffs, estimates, and bid-ready proposals in one unified interface—so you can go from plan to proposal without switching tools.
Why does it matter?
Switching between tools slows you down and increases the risk of errors. STACK streamlines your entire workflow so you can move from plan to proposal without missing a beat.
